Abstract

L'invention concerne l'utilisation de grains sphériques ou sphéroïdaux en diamant, en nitrure de bore cubique (NBC) ou en matériaux céramiques structurés pour produire des éléments structuraux et des composants en micromécanique, en microélectromécanique, en technologie des capteurs et médicale, en tribologie et dans des domaines apparentés. On les utilise par exemple pour produire des roulements à billes et des surfaces de glissement à frottement et à usure réduits, des soupapes à billes, des robinets à boisseau sphérique, des pompes sous-millimétriques et des micropompes, des micropompes de refoulement de quantités minimes de gaz, de poudres ou de liquides, ainsi que pour produire des micropistons et des microseringues de haute précision pour l'injection de volumes allant d'1 mu l jusqu'à moins d'1 al(1<.>10<-18>1).
